Operating notes
The RDE100.. provides Comfort, Economy, Auto timer and Protection mode. The
difference between Comfort and Economy mode is only the room temperature
setpoint. The changeover between Comfort, Economy and Protection mode is
made either automatically by the auto time switch or by pressing touchkey mode.
When Comfort mode is activated, symbol appears on the display. The setpoint
(20 ºC) can be readjusted by pressing touchkeys + and –.
When Economy mode is activated, symbol appears on the display. The setpoint
(16 ºC) can be readjusted by pressing touchkeys + and –.
In RDE100.1, a window contact feature is that a user can connect a window
contact to the input X1, . Depending on whether the window contact is
configured to Normally Open or Normally Close (Parameter P14 = 2, Parameter
P17 = 0 or 1), a change in this status will automatically switch the thermostat from
any modes to Economy mode. This feature is good for public area. The factory
setting for this function is Off (disabled).
If the temperature falls below 5 ºC, the unit automatically activates the heating
output. The symbol
appears only, if the icon is enabled via parameter settings.
When Auto timer mode is enabled, the changeover between the operating modes
(Comfort and Economy mode) will take place automatically. There are three
options for time switch setting: individual day, 7 day or 5-2 day. You can select
Comfort or Economy mode in every 15 minutes interval of the day. The 0:00 to
24:00 hour time bar will allow you to set the mode throughout the selected day(s).
